Membrane biological reactors combine activated sludge treatment with a membrane liquid- solid separation process. The membrane component utilizes low – pressure micro filtration or ultra filtration membranes and eliminates the need for clarification and tertiary filtration. The membranes are typically immersed in the aeration tank.
